To all who-m it may concern:

Beit-known that I, JULES at Vermilion, 1n the county of Clay an State of South Dakota, have invented certain new and useful Improvements in a Double Envelope; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itv appertains to make and use the same.

The object of the invention is to provide a double or I pockets of coextensive area and either or both of which may be sealed or closed, and which can be used successively for a message and the answer thereto, the fold forming the outside of the pocket or compartment which is sealed and used for the outgoing message being adapted to be torn off and the remainder of the package consisting of the other pocket orreceptacle used for the return message and which in turn may be sealed to protect the message; and more particularly the object is to provide a package of this type which can readily and economically be constructed from a substantially rectangular blank of paper to avoid waste in cutting;- and with these objects in view, the invention consists in a construction, combination, and relation of parts of which a preferred embodiment is shown in the drawing, wherein: I

Figure l is a front view of an envelope embodying the invention.

Figure 2 is a plan view of the blank from which the envelope is formed.

Figures 3 and 4 are sectional views showing the blank loosely folded in opposite direction and indicating optional ways in which the receptacle can be formed from the same blank.

Figures 5 and 6 are transverse sectional views of the completed envelope folded as indicated respectively in Figures 3 and 4.

Figure 7 is. an enlarged sectional view of the top of the envelope showing one compartment sealed and the other unsealed for succeeding use in connection with a return message,

Figure 8 is a similar view ofthe upper end of the envelope showing-the previously sealed compartment removed and the previously unsealed compartment sealed to conmin and protect the return message.

Figures 9- and 10 are enlarged etail sec- Ml NEss, a citiate fold 20 and plural pocket envelope having finished envelope.

tional views of the lower end of the envelope folded respectively as shown in Fig ures- 3 and 4. l

The envelope is formed from a blank as shown'in Figure 2 consisting of an intermediterminal folds 21 and 22 which are of corresponding area or are coextensive when folded into superposed relation, and the terminal folds are provided at their outer edges withside sealing flaps 21 and 22 The terminal folds, in the fin-. ished envelope, are arranged upon opposite sides of the intermediate fold, as indicated in Figure 3, and are gummed on their opposite,

by the shading. When surfaces-as indicated the terminal folds'are arranged upon the same side of' the intermediate fold 20, as shown in Figure 4, they are gummed on the same side, and when folded each side securing flap is folded in between the fold by which it is carried and of which it forms a part and the adjacent fold. It is adhesively secured to the latter so as to leave the full width of the fold to form the compartment or pocket of the envelope as will be seen by reference to Figures 3 and 4 and 5 and 6.

The intermediate posite ends with closing flaps 24 and 23 which respectively constitute a covering or sealing flap and a bottom closing flap, while the terminal folds are provided at opposite ends with closing flaps 26 and 25, the former of which constitutes a covering or sealing flap, while the latter constitutes a bottom flap to close the lower end of one of the compartments or pockets of the The ends of the terminal folds opposite to the flaps carried thereby as above indicated may be cut away as indicated respectively at 26 and 25 mainly to lightenthe weight or avoid bulkiness at the ends of the finished envelope and at the same time give ready access to the contents of the pocket, it being iinderstood that as the blank is symmetrical so far as the construction at the ends of the folds are concerned, either end may be closed in the first instance to form the bottom of the envelope and leave the flaps at the opposite end to constitute the pocket or compartment closing means.

In other words not-only can a blank constructed as described be folded in a plurality of ways as indicated in Figures-3 and 4 to form the separate pockets or compartments, the separating wall between the comfold is provided at opend thereof to be used as the sealing either of which may be partments consisting of the fold 20 or one of the terminal folds as may be preferred,

but either of the end flaps disposed at the,

extremities of'thefolds may be turned in and sealed to close the bottoms of the pockets or compartments of the finished envelope, leaving the flaps at the opposite flaps,

. ing flap by which the message placed therein maybe protected.

Having thus described the invention, what I claim is 1. A double pocket envelope consisting of ablank having an intermediate and termlnal coextensive folds and gummed fastening sealed when a mes-- flaps at the remote edges of the terminal folds, the intermediate fold being provided at opposite ends with closing flaps and each of the terminal folds being provided at one end with a closin flap.

2. A double poo et envelope consisting of a blank havin an intermediate and terminal coextensive folds and gummed fastening flaps at the remote edges of the terminal folds, the intermediate fold having terminal corresponding sealing and bottom flaps and the terminal folds respectively hating a sealing and a bottom flap.

3. A double pocket envelope consisting of a blank having an intermediate and terminal coextensive folds and gu-mrned fastening flaps at the remote'ed es of the terminal folds, the intermediate old having terminal corresponding sealing and bottom flaps and the terminal folds respectively having a d sealing and a bottom flap, arranged respectively at opposite ends thereof.

In testimony whereof I ailix my signature in presence of two witnesses.
